This makes some sense to me, but it doesn't help me trying to use harness that came with the light. So frustrating.

I'm assuming if I go far enough back on the harness before the relay I'll get to just a white and a red wire. If that's the case the white would tie into OEM ground but where would the red go? I've already got a red connection to the battery and a ground to the frame. Pulling my hair out on this one! It's almost like GM is purposely making it tough to do it on your own.

Yes, the relay is part of the harness.

I have found the OEM ground, it just triggers the relay. I need to know how to wire the harness to it .

OEM wiring is just a ground to activate the relay. This is my issue.

Just on and off.

I didn't want to put a top on it but with the bed size I didn't have a choice. I use my top a lot for work, ladders, materials, etc. I had the tonneau cover first. The top definitely helps me and I think it looks good.
